PACKING AND FEFRlGll-IRATING` VESSEL.

SPECIFICATION forming part of Letters 'Patent No. 431,941, dated July 8, 1890.

.Application tiled January 30, 1890. Serial No. 338,633. (No model.)

To all whom it may concern:

Be it known that we, LUTHER L. FRrERsoN and JACOB BARKER, citizens of the United States, residing, respectively, at Mount Pleasant and Columbia, in the county of Maury and State of Tennessee, have invented new and useful Improvements in Packing and Refrigerating Vessels, of which the following is a specification.

This invention relates to thattype of packing and refrigerating'structures for preserving and transporting poultry, milk, and other food products wherein a closed containingvessel is arranged in an envelope or external casing, with an antiseptic packing between the two, as -in Letters Patent No. 410,481, issued September 5, 1889.

The objects of our invention are to improve the prior constructions, and to provide novel, simple, and efficient means for retaining the containing-vessel in a fixed position relatively to the envelope, and at the same time form part of the bottom wall of the ice-chamber.

The objects of our invention we accomplish by the features of construotionand the combination or arrangement of devices hereinafter described in detail and specifically set forth in the claims, reference being made to the accompanying drawings, in which- Figure 1 is a vertical central sectional view of a packing-refrigerator embodying our invention; Fig. 2, a similar view of the upper end portion of the structure, showin g a modiication; and Fig. 3, a broken sectional view showing a variation of the parts exhibited in Fig. 2.

In order to enable those skilled in the art to make and use our invention, we will now describe the same in detail, referring to the drawings, wherein- The numeral 1 indicates an external casin g that we terni an envelope, and which may be polygonal or any other desired shape in cross-section, but is preferably circular and ot' the same general coniiguration as an ordinary barrel. This envelopeis coated by painting or otherwise internally and externally with a proper water-proof material for preserving the wood and preventing it from becoming saturated with water. The containing-vessel 2 is preferably of metal, and is provided with an inclined breast 3, from which rises a neck 4, that receives the ti ghtly-ittin g cover 5, and the envelope is furnished with a tight cover 6, detachably held in position by fastenings T-such, for example, as described and shown in the Letters Patent before mentioned. The space between the external sides and the bottom of the containing-vessel and the interior of the envelope is iilled'with an antiseptic packing of charcoal or other inaterial suitable forV the conditions required, which packing terminates at or near the point where the breast 3 joins the side of the containing-vesself An annular ring or band 8 is rigidly secured to the inner side of the envelope directly above the antiseptic packing to form a lateral shoulder that supports the outer edge portion of an annular plate 9, formed with a central circular openin g, through which the top portion of the containing-vessel projects, so that the inner edge 10 of the plate rests upon the inclined or conicalbreast 3, and to which said inner edge is soldered or otherwise firmly attached. rThe annular plate inclines downwardly from itspoint of attachment to the breast 3 to the shoulder formed by the annular ring or band 8 in such manner thatwater resulting from melting ice in the ice-chamber 12 will flow outward toward the envelope and through orifices 13 in the plate, sol as to percolate down through the antiseptic packing. The outer edge of the annular plate is turned upwardly to form avertical ilange 14, which preferably extends entirely around said plate, and this flange engages a movable retaining-clamp, which, as shown in Fig. 1, is composed of a ring or band 15, secured to the inner side of the envelope directly above the band 8 in such manner that the iiange 14 is between the ring 15 and the envelope, while the lower edge of said retaining-ring 15 holds and clamps the annular plate 9 iirmly against the top edge of the band 8. By this means the containing-vessel is held in a stationary position in relation to the envelope, and it' the latter be overturned or severely handled the containing-vessel will not be displaced. The bottom of the envelope is provided with escape-openings-one or more-closed by stop- IOO pers or plugs 16 for discharging the ice-water as occasion requires.

In the construction above set forth the containing-vessel is not intended to be removed and replaced at will, although such is possible by detaching the retaining and clamping ring or band 15, provided, of course, the internal caliber of the envelope is as great from the band 8 to the top edge of the envelope as the diameter of the annular plate.- XVe have, however, shown the envelope as we prefer to construct it when the container is not adapted for removal. It is sometimes desirable to provide for removing and replacing the containing-vessel without entirely detaching the clamping device that secures the annular inclined` plate on the supporting ring or band 8 we provide the construction shown in Fig. 2, where 4Jthe outer edgeof the annular plate 9 is wired, as at 17, and vrests on the-ring or band 8,'while above the latter are pivoted by pinsl 18 the retaining clamp-plates 19, each having at its lower edge a flange or shoulder 20 to bear against the wired edge 17 4and clamp andhold it firmly againstfthe supporting ring or band 8. In this construction we prefer to construct the annular plate =in sections, cach section being segmental, to permitthe plate being conveniently removed and replaced. The inner edge 10 of the plate, in- Stead'of being rigidly secured tothe inclined or conical breast 3 of the containing-vessel 2, is detachably connected with' said breast by spring clamping arms or fingers 21,-secured to bearing-plates 22,. that are xed on the breast 3. plates 19 on'their pivotspins 18 to disengage their shouldered or flanged ends 20 from the wired vredge 17 the latter can be raised and the annular plate be thereby removed from under the spring arms or lingers 21, after which the containing-vessel can be lifted out of the envelope.V The bearing-plates 22 form shoulders or'abutments for the inner edge of the annular plate 9 when the latter is inserted under the spring arms or fingersv 21, and thus the containing-.vesselv can be firmly secured in a ixed position within the envelope whilev permitting Lits convenient removal when desired.

In Fig.l 3 We show the annular plate E) inclined downward from the band 8 to the inclined breast 3 of the containing-vessel 2, and at its inner lower edge formed with a flange 28, resting on the breast 3 and abutting the bearing-plates 22.

The construction of the envelopev l, spring clamping-arms 21, clamp-plates 19, and other parts not particularly mentioned, is the same as described with reference to Fig. 2.

B y lturning. the retaining .clamp- The arrangementshown in Fig. 3 is very desirable, .in that the annular plate 9 operates more effectually as a brace to retain the oonta'ining-vessel in correct position should the envelope be overturned.

Having thus` described our invention, what we claim is'- 1. Apacking-refrigerator consisting of an envelope having a ring or band secured to its inside, a con taining vessel having an inclined breast and tight cover, an inclined annular plate provided with orifices resting at its outer edge on the ring or band and connected at its inner edge with the inclined breast of the containing-vessel, and a retaining-clamp for engaging the outer edge of the said annular plate and clamping vit on the ring vor band, substantially as described.

2. A packing-refrigerater consisting of any envelope having on `its inner side a shoulder, a containing-vessel provided with an inclined breast, an antiseptic packing between the envelope and containing-vessel, an inclined annular plate resting at its outer edge on the said shoulder, connected at its innery edge with the inclined breast of the containing-vessel and provided with orifices for the passage of :water .to theantiseptic packing, and a clamp engaging the outer edge `of said'plate andlholding itfupon the said shoulder on the envelope; substantially as described.-

3. A packing-refrigerator consisting of any envelope having a shoulder on its inner side, a containing-vessel having an inclined breast provided with movable arms or` fingers,ian annular perforated plate engaged at its-inner' edge bythe arms or fingers, and movable -retaining-platesclamping the outer edge-of the plate -upon the shoulder on v'the envelope, substantially as described.

ll.V AV packing-refrigerator consisting of :an:

envelope having a ring or bandsecured to .its inner side, a containing-.vessel havlng'an inf clined breast provided with bearing-platesand spring arms or lingers, an annular perforated plate engaged at its inner edge by the bearing-plates and the arms -or finge-rs and resting at its outer edge upon the ring-or band on the envelope, and pivoted retainingplates clamping the outer edge of the i plate on said ring or band,'substantially as described.
